Your efs folder is corrupt, pay for a repair or use a patched modem and kernel in 4.3

Do you know if your s3 ever had imei issues, got unlocked through means other than imei code, or did you ever used patched modem (or ariza)?

If yes, stay on 4.1.2, or do as adviced and get a patched modem and kernel for 4.3.

Your efs might be damaged, to stay on the safe side, backup everything before attempting to upgrade or patch stuff.
